In the early 2000s, Italian beekeepers began to report bee mortality events linked to maize sowing. Evidence pointed to three neonicotinoids (imidacloprid, clothianidin, thiamethoxam) and a phenylpyrazole (fipronil) used for seed dressing that were dispersed in the environment during sowing.

Heritabilities and genetic correlations were estimated for honey yield and behavioural traits in Austrian honey bees using data on nearly 15,000 colonies of the bee breeders association Biene Österreich collected between 1995 and 2014.

Selection of honeybee strains resistant to the ectoparasitic Varroa destructor is  considered as one of the most sustainable ways of coping with it.

Himalayan cliff bee is the largest honeybee of the world which bears only a single large colony at open space and is native to Nepal.

Lithium chemicals have been proven to be very effective in eradicating Varroa destructor, the detrimental parasite of the honey bee.

The genetic variation of N. ceranae supports the hypothesis that the most likely origin of N. ceranae was East Asia, and then spread through the world.

Honey bees provide critical pollination services for many agricultural crops. While the contribution of pesticides to current hive loss rates is debated, remarkably little is known regarding the magnitude of risk to bees and mechanisms of exposure during pollination...

The natural distribution of the honeybee (Apis mellifera L.) has been changed by humans in recent decades to such an extent that the formerly widest-spread European subspecies, Apis mellifera mellifera, is threatened by extinction through introgression from highly divergent commercial strains in large tracts of its range.

Stored pollen is the nutritionally rich currency used for colony growth and consists of 40–50% simple sugars.

Colonies with typical honey bee depopulation symptoms were selected for multiple possible factors to reveal the causes of collapse.
